I have the grid move command on my shortcut bar as something the player has to activate when they want to use it. However, I've noticed that if you activate the grid move command and end the phase, the highlights will disappear and not reappear however the grid move command will remain active (selected).
After the phase ends and the highlights disappear, I cannot click and move. I want to click the grid move command once to deactivate it and then click it again to reactivate it and trigger the highlights to appear.
I've only tested this with "end phase", but I would assume if you ended the individual turn of the selected combatant a similar thing might happen, so I think it is worth checking if this situation occurs if you just end the turn of the combatant too as opposed to the entire phase.
